The raw materials for the soft spoon are mainly thermoplastic rubber and silica gel. Thermoplastic rubber, also known as thermoplastic elastomer, is a material that combines the properties of rubber and thermoplastics. Thermoplastic elastomers can process rubber articles as quickly, efficiently, and economically as thermoplastics. In terms of processing, it is a kind of plastic; in terms of nature, it is a kind of rubber. Thermoplastic elastomers have many advantages over thermoset rubber.

      Silica gel, a name silicone rubber, is a highly active adsorbent material, which is an amorphous substance with a chemical molecular formula of mSiO2?nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Silicone is more suitable for use in food grade materials such as baby soft spoons and baby pacifiers. It is colorless, non-toxic, highly transparent, and does not produce toxic substances in water.
